Well, we have to say, that mug shot isn't exactly the picture of remorse.

Former "The Bachelorette" contestant
Kasey Kahl -- you'll remember him as the one who swore to "guard and protect" Ali Fedotowsky's heart, then dated Vienna Girardi, then
fake-dated Vienna Girardi -- was arrested on Sunday morning at a nightclub.

TMZ
reports that Kahl "attacked" a man named Richard Chaney outside the club, then "smashed" his girlfriend, Renee Idsinga, in the face when she tried to break up the fight. (Word is, Kahl was loudly and publicly claiming to have slept with one of Renee's friends.)

Renee told police that she had scratched Kahl's neck, and then he punched her in the face and caused her nose to bleed.

Kahl's publicist released the following statement:

"At this time we have no comment regarding the specific facts of the alleged incident, but we are confident that Kasey Kahl will be fully exonerated upon completion of a full investigation. We merely ask for patience until such a time that those facts can be brought forth. As Kasey is in the public eye, it is not unlikely that we would not be surprised if these persons bent on attaining their 15 minutes of fame, while intoxicated and perhaps fueled by jealousy, will antagonize and attack stars such as Kasey in a 'Jersey Shore' type brawl given the opportunity. These persons wanted their 15 minutes, which they received, and now those 15 minutes are over. The recent reports emphasizing any brutality on his behalf and downplaying his act of self-defense are entirely speculative and false. Kasey's lawyers will vehemently confront and respond to any and all defamatory, slanderous, and or libelous statements or claims and will defend him to the fullest extent of the law."
